CEILING-LIGHT.

Specification of Letters Patent.

Patented May 31, 1921.

Application filed August 10, 1916. Serial No. 114,109.

To all whom it may concern:

Be it known. that I, LAURITZ W. ANDERSEN, a citizen of the United States, residing. at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in. Geiling- Lights, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to electric light fixtures and more particularly to a ceiling light especially adapted for the ceilings of porches, corridors and the like.

One object of the invention is to provide a very simple device capable of receiving either a porcelain receptacle or a lamp socket of ordinary construction, and another object is to provide a device upon which closed glass-ware can be securely fastened without the aid of screws or threads.

Another object is to provide a ceiling light fixture which will be dust, dirt and insect proof and at the same time thoroughly ventilated. A still further object is to Provide a ceiling light fixture in which the locking element can be moved up and held out of place giving the operator the free use of both hands in placing or removing the globe or glass-ware.

With these various objects in view the invention consists in the details of construction hereinafter fully described and pointed out in the claims.

In'the drawings forming a part of this specification, Figure 1 is a sectional perspective illustrating one practical application of my invention; Fig. 2 is a detail perspective view of the canopy'and supporting portion; Fig. 3 is a detail perspective vlew of the locking shell; Fig. 4 is a detail perspective view of the wire gauze band removed from the canopy; Fig. 5 is a horizontal sectional View of the device; and Fig. 6 is a detail section.

In the practical embodiment of my invention I employ a canopy or box like member A which ma be of any desired size or shape and which is adapted to be secured to the ceiling by means of screws passed upwardly through the apertures A produced in the horizontal flange portion. of the canopy or box like member. This canopy has a circular portion B which holds or contains the upper and enlarged portion of the porcelain receptacle G, the depending portion of said porcelain receptacle fitting into the decarried at the lower end of the-tubular depending portion D, this flange being cut away upon opposite sides as shown at F so as to permit the mouth of the shade or globe G to be passed thereover and arranged thereon, the projecting portions F engaging the interior of the globe or shade as shown and supporting the same; it being understood that in attaching theshade or globe it is tilted so as to be passed first over one projecting portion F 2 and moved sufficiently toward the center to permit the opposite edge of the globe or shade to be brought up over the opposite projecting portion F and then by centering the globe or shade it will rest firmly upon. the fixed supporting flange.

In connection with the supporting flange I provide a locking shell H which is adapted to be brought into engagement with the exterior of the shade or globe after the same has been arranged upon the supporting flange, and for the purpose of locking this shell in engagement with said shade or globe I construct the upper portion of the shell with a plurality of inwardly extending inclined ribs I, three such ribs being preferably employed. At equidistant points upon the circular box like portions B I produce vertical ribs K and in alinement with said ribs and beneath the same a plurality of projections or protuberances L, these projections or protuberances being adapted to be engaged by the inclined ribs upon theshell for the purpose of locking the ring upon the shade or globe and by providing aplurality,

preferably three, of such projections various thicknesses of glass-ware can be accommodated.

By providing the inclined ribs I at equidistant points and leaving the intervening spaces smooth it is possible to move the shell' upwardly so as to carry the same entirely clear of the mouth of the glass-Ware and then by turning the shell so as to bring the inclined ribs above the upper ends of the vertical ribs the shell can be held locked portion is also provided with ventilating openings N, and in orderto guardagainst insects and dust and dirt I arrangeaband O of wire gauze within the box portion B covering the ventilating openings M and it will not be necessary to cover the openings N as the shell H contacting with the glass-ware will prevent the entranceof insects and dust and dirt through these openings. The band of wire gauze is cut the proper size to exactly fit the interior of the circular box portion l3 and can,ii' desired,

be secured by solder or any other suitable Inannenf A device constructed as herein shown and described is a complete unitary device enibodying a safe and reliable shade holding means adapted for use in connection with either open or closed glass-ware. The device also includes lamp socket securely united to the canopy or fastening means and in connection with these parts is the locking member for securely fastening the glass-ware after the same has been properly positioned and it will he noted that all of these parts are constructed and arranged with the view of ease and accuracy of manipulation and with the view of avoiding the use of screws or threads such as heretofore employed in devices of this character.

Having thus described my invention, what I claim is:

1. In a light fixture a socket holder hav-v ing a circular portion provided with a vertical rib and a plurality of projections be neath said rib and in line therewith, a shade holding flange spaced beneath said circular g'lassportion and connected thereto, and a shell 46 having an inclined rib adapted to engage the projections or ribsupon the circular portion as set forth.

2., A light fixture comprising .a .socket holding portion and a shade holding flange spaced beneath the same and connected there to, said socket holding portion having screened ventilating openings, ribs and projections .upon said circular portion, and a shell" surrounding said circular portion and having inclined ribs adapted to engage the projections and ribs upon the circular portion, said shell being movable toward and away from the shade supporting flange as set forth.

3. ceiling light comprising a socket holding portion having a shade supporting member at the lower end thereof, said socket holding member having a plurality of ventilating apertures, a screen for covering said apertures, and a shell arranged upon said socket holding portion and movable axially thereon together with means carried by the socket holdingportion and shell for holding said shell in either the raised or lowered position.

4. A light fixture comprising a socket holding portion and a shade holding flange spaced beneath the same and connected thereto, ribs and projections upon said socket holding portion and a shell surrounding said socket holding portion and having inclined ribs adapted to engage the projections and ribs on the socket holding portion, said shell being movable toward and away from the shade supporting flange.

' In testimony whereof, I hereunto afix my signature in the presence of two witnesses.
